Product Detailed Description:

HTL6054YesHuatech SemiconductorA newly launched product4 sets of lithium battery protection chipsSpecifically designed for multi-section lithium-ion/polymer battery packs, offering comprehensive safety protection features. Its features include:Adjustable Overcurrent ProtectionAndTemperature CompensationBattery Management Systems suitable for high-reliability requirements.

Core Functions

  1. 4 battery protection strings
  • Support4S in SeriesLithium-ion/Lithium-polymer battery packs, single cell voltage range:2.5V–4.35V。
  1. Adjustable Overcurrent Protection
  • Flexible setting via external resistanceOvercurrent threshold for charging/dischargingAdaptable to various load requirements.
  1. Temperature Protection and Compensation
  • Built-in high and low temperature protection function, supports external thermistor to adjust temperature thresholds (such as)-20°C~60°CAdjustable).
  1. High-precision voltage monitoring
  • Real-time monitoring of each cell's voltage to prevent overcharge (OVP) and over-discharge (UVP), accuracy up to±25mV。
  1. Low-power design
  • Very low standby current (typical value)<3μA), suitable for portable devices.
  1. Fault Indicator
  • ThroughSTAT pinOutput abnormal conditions (such as overvoltage, undervoltage, overheating).
